How long is a 90-minute video at 1.25x, 1.5x, 2.0x, 2.5x, or 3.0x speed?

When you’re researching or watching content on a specific topic, you might come across long-form videos, like 90-minute ones. You may want to save time by speeding them up, but if you’re feeling unsure, don’t worry.
In this post, I’ve shared my research and precise calculations for a 90-minute video at 1.25x, 1.5x, or even 3x speed.
I’ve also put together a list of tips and tricks for watching, calculating, and choosing the best playback speed.
Personally, I use YouTube to watch content about language learning, productivity, entertainment, and education. And I’ve found that you shouldn’t set the same playback speed for all types of content. Using the wrong speed can actually harm your learning experience.
For example, if you’re watching a 90-minute educational video at 2x speed, you’ll finish it in 45 minutes, saving 45 minutes of time. But you may end up missing important information. In this case, it’s better to stick with 1.25x or 1.5x in some situations.
Later on, I’ll share some tips for picking the right playback speed.

Playback Speeds for a 90-Minute Video
To explain how playback speeds work, let’s use a 90-minute video as an example. Here’s a simple table showing how long it would take to watch at different speeds:
Original Video Length | Playback Speed | Time to Watch | Time Saved |
---|---|---|---|
90 minutes | 1x (Normal Speed) | 90 minutes | 0 minutes |
90 minutes | 1.25x | 72 minutes | 18 minutes |
90 minutes | 1.5x | 60 minutes | 30 minutes |
90 minutes | 1.75x | 51.4 minutes | 38.6 minutes |
90 minutes | 2x | 45 minutes | 45 minutes |
90 minutes | 2.25x | 40 minutes | 50 minutes |
90 minutes | 2.5x | 36 minutes | 54 minutes |
90 minutes | 2.75x | 32.7 minutes | 57.3 minutes |
90 minutes | 3x | 30 minutes | 60 minutes |
90 minutes | 3.5x | 25.7 minutes | 64.3 minutes |
90 minutes | 4x | 22.5 minutes | 67.5 minutes |
Why adjust playback speeds?
By adjusting the playback speed, you can control how fast or slow you watch. Speeding it up saves you time, while slowing it down helps you understand tricky topics better.
Find Your Ideal Speed
From my own experience, I’ve learned that not all content is created equal when it comes to speed. Here are some tips for choosing the right speed:
- Familiarity Matters: If you’re well-versed in the topic, you can often bump up the speed without losing comprehension. For example, I often watch review videos at 1.5x or even 2.0x to refresh my memory quickly.
- Complex Topics Require Slower Speeds: For subjects that are dense or new, like advanced mathematics or technical tutorials, stick to 1.0x or 1.25x. Slowing down helps with understanding and retention.
- Experiment: Don’t hesitate to try different speeds. It’s a personal choice, and what works for one person might not work for another. Adjust according to your comfort level.
Benefits of Higher Playback Speeds
- Efficiency: You can save time by consuming more content in less time. At 2.0x speed, you can watch a 90-minute video in just 45 minutes!
- Enhanced Focus: Watching at a faster speed can help you stay engaged and minimize distractions.
- Improved Learning: For those already familiar with the material, faster speeds can reinforce knowledge and make reviewing more efficient.
